... fabricating ultrafast axial nano-oscillators based on carbon nanoscrolls (CNSs) using molecular dynamics simulations. Initiated by a single-walled carbon nanotube (CNT), a monolayer graphene can continuously ... velocity 2.5 Å/ps along its axial direction to initiate the oscilla- tion. In order to constrain the rigid body motion of the nano-oscillator, two rows of carbon atoms a...
